Abstract

Persaingan industri yang semakin ketat menuntut setiap perusahaan terus memperbaiki aktivitas operasional lebih optimal. Penelitian ini bertujuan untuk menentukan tindakan perawatan optimal dan menentukan interval waktu perawatan pada Mesin Bubut CY-L1640G pada departemen Maintenance di PT. Polymindo Permata, dimana masih banyak kegiatan perawatan korektif disebabkan kerusakan mesin. Agar tujuan tercapai penulis melakukan analisis secara detail menggunakan metode Reliability Centered Maintenance (RCM), dengan aplikasi awal mengetahui fungsi serta kerusakan yang dapat  terjadi pada suatu sistem, mulai dari sub-sistem sampai pada level komponen. Tabel FMEA untuk penentuan komponen kritis, analisa Intermediate Decision Tree (IDT) untuk mengetahui dampak kegagalan baik langsung maupun tidak langsung,  kemudian analisis Logic Tree Analysis (LTA) untuk menentukan tugas perawatan yang optimal. Hasil yang didapat adalah pemecahan masalah dimana perusahaan harus melakukan interval perawatan pada komponen Electric System dalam rentang interval 255.07 jam atau 32 hari kerja. Untuk mengetahui tingkat kerusakan komponen dengan melakukan tindakan Condition Monitoring, untuk mengatasi kegagalan yang tidak dapat diprediksi dengan melakukan tindakan Corrective Maintenance dan untuk mengatasi kegagalan yang dipengaruhi usia komponen dengan melakukan tindakan penggantian yang terjadwal.

Abstract

Competition in the industry is getting tougher, and companies are required to make improvements in various departments, one of which is the maintenance department which supports system operations so that they run as desired. PT. Valvindo Mitra Raya which is engaged in Water Pipe Installation and Machanical Repair/Reconditioning. Until now, preventive maintenance activities are scheduled every year, but the maintenance department still carries out many corrective maintenance activities. This final project aims to determine the optimal maintenance action and determine maintenance intervals on the Gate Valve machine. In order to achieve the goal of writing, perform a detailed analysis using the Reliability Centered Maintenance (RCM) method, where the initial application is to find out the functions and damage that can occur in a system, starting from the sub-system to the component level, FMEA table for determining critical components, for determine the direct or indirect impact with Intermediate Decision (IDT) analysis, and then to determine the optimal maintenance task through Logic Tree Analysis (LTA). The results obtained are in the form of problem solving, namely the company performs machine maintenance intervals on Disc components with maintenance intervals of 224.39 hours or 32 working days, with the aim of knowing the level of component damage by carrying out Condition Monitoring actions, to overcome unpredictable failures by performing Corrective Maintenance actions and to overcome failures that are affected by the age of components, scheduled replacement actions.

Abstract

The smooth running of a system or a production process requires support from several aspects, including machine maintenance and machine availability in the production system. Maintenance includes the efforts made to ensure the machine works well, effectively, efficiently, economically, functionally and optimally. Therefore we need a good maintenance management in order to support maintenance activities, this study aims to determine the effectiveness and the biggest problem that causes downtime on the extrusion machine. The steps taken to implement it are measuring Overall Equipment Effectiveness (OEE) and knowing the biggest factors that affect the calculation of the six big losses. The world class productivity standard formulated by the Japan Institute of Plant Maintenance (JIPM), is 85%. The results of the current OEE measurement show that the productivity of the extrusion machine is 76.18%. This value indicates that it does not reach the worldclass standard value.
